About Boomstone

Three red gems were enough to meet Boomstone’s first target in both tested sessions. Select the gems labelled 3, 5 and 7, then press Blast: those three positions emptied, and the final panel showed Level Score 90/60. The Blast counter fell from four to three. This is an observed opening combination, rather than a solution for every board.

Before blasting, watch the changing preview. Selecting a single red gem showed about 8; adding the second changed it to Color Pair Red and about 23. With all three selected, Color Trio Red previewed about 90. The board accepted native touch taps and desktop mouse clicks. Intermediate score frames showed 66 or 70 before the final 90 settled.

On a phone, the mining guide’s score explanation was cut off at the bottom. The gem grid, Blast button and Target Met result stayed visible. The result also listed Earned +18, but we did not choose Supply Post or test its purchases. Swap, later layers, other combinations and saved progress remain untested.

Why it's Chromebook-friendly

The measured entry-referenced core is 0.6 MB. Native touch and mouse inputs each selected the red gems marked 3, 5 and 7, then used Blast to clear their positions. Both recorded first targets finished at Level Score 90/60 with Earned +18. The first after-Blast totals of 66 and 70 were animation frames, not final results. On a phone, the mining guide’s explanation bubble is clipped at the bottom; the gem grid, Blast control and Target Met result remain visible. Supply Post, gear purchases, Swap, later layers, the complete eight-layer run and saved progress were not tested.

Known quirks
